In the space below, draw a firm’s isocost/isoquant diagram with K on the vertical axis and L on the horizontal axis.

1. Show the change that would occur if capital became more expensive and the firm maintained the same total cost.  Be sure to show how each curve changes.  To the right of the graph, clearly indicatewhat happens to the level of output and use of both L and K, and whether you are showing L and K as substitute inputs or complementary inputs.

2. Draw another isocost/isoquant diagram below.  Consider the same increase in the cost of capital.  However, this time, assume the firm maintains the same level of output, so it stays on the same isoquant as the price of capital increases. Show what would change in the graph and to the right of the graph, clearly indicatewhat happens to the firm’s total cost and its use of both L and K.

1. Calculate the annual economic growth rate of country A.
2. Approximately, how long will it take for the real GDP per capita of country A to double?
3. The country discovered a new oil field, but economic growth rate fell afterward. Explain how this could happen.
4. For each of the following separate policies, determine the associated factor of economic growth.

• People have a tendency to categorize others into hierarchies. What do you all think has been the source of racial hierarchies in the United States? Do these hierarchies have any validity? Why or why not?

• As you are learning, race is not the simple product of biology (such as the physical features that someone possess), but is actually the result of the ways that society defines how these outward features acts as signs, carrying culturally constructed meanings. Do you agree with this view that race is a cultural construction? Why or why not? Give an example to support your opinion.
